LAPPlNe-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 723,272, dated March 24,1903. Application iiled January 14,'1901. Serial No. 43,238. (No modeL)To @ZZ wwT/t it. may concern: l

Be it known that I, ROBERT J. HILL, a citizen ofthe United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Machines for Forming Bats, of which the following is aspecification.

My invention consists of a lapping device` operating on the well-knowncamel-back principle, but varying from the latter in certain parts andhaving certain additions whereby it is adapted for making laps Of anywidth and various thicknesses, `such as are employed in the manufactureof mattresses,

quilts, comfortables, cushions, carpet-lining, .g

stairpads,commercial bats, &c.

The special object of my invention is to provide a lapping device ormachine having a wide range of application and which will simplify andimprove the process of making said laps. The machine is adjustable toany wid th of lap, thereby enabling me to deposit agood grade of stockon the transverse apron by one carding or garnet machine, an inferiorgrade of stock on top of that by a second machine, and by a thirdmachine to cover this again with good material, thus producing afine-surfaced bat at the least expense. y

In the accompanying drawings, Figure 1 is a side view of sufcient ofabat-forming machine to illustrate the invention. Fig. 2 is an end Viewof the same looking in the direction Fig. 3 is a View on a larger scalethan Fig. 2, illustrating a part of the machine forming a continuationof that there shown. Fig. 4 is an end view looking in the direction ofthe arrow w, Fig. 3. Fig.

Fig. 1 0 is a diagram illustrating the method in which the device isused to form a multiple bat. j

In Fig. 1 part ofthe apron of a cai-ding or garnet machine isrepresented at l, this apron delivering its web or ieece onto an endlessslatted conveyer apron or belt 2, which passes around four drums 3, 4,5, and 6, the drum 3 frame 7, having rollers 8, which run upon` railsformed by beams or girders 9, mounted upon frames 10, said frame 7engaging with pins projecting from endless belts or chains 1l, one ateach end of the frame 7. These chains at points adjacent to theconveyerbelt 2 are carried and driven by sprocketwheels on short shaftsmounted in bearings in the beams 9 and each driven by-means of a chainbelt 12 or other suitable power-transmitter from a Wheel or pulley onVthe shaft of the drum 3, to which shaft power is applied by another'chain belt or equivalent power-transmitter 13, driven by any availableshaft of the carding or garnet machine. Back-and-forth reciprocation isthus imparted to the frame 7 to an extent equal to ,the length of thebelts 11, and as the distance between the drums 3 and 6 is thusconstantly varying there is a corresponding rise and fall of theintermediate drums 4 and 5, which support4 the conveyor-apron 2, and inorder to permit this the shaft of the upper drum 4 is carried `by theupper ends of a pair of bars 14, one pivoted at its lower end in lineaxially with the shaft of the drum 3 and the other pivoted at its lowerend to the carriage 7 in line axially with the shaft of the drum 6, theupper ends of the hars being connected together in line axially with theshaftof the drum 4. The shaft of the drum 5 is adapted to bearingsl5,movable vertically in a bracketplate 16, secured to one of the bars14, said bearing-boxes being supported upon springs 17, so that theconveyer belt or apron4 2 is `kept under proper tension inall of thevarying angles in respect to eachother assumed by the bars 14 of thecarrying-frame.

At each of the ends of the beams 9 are elastic buffer-pins 80, projectedby springs 81, contained in sockets 82, which form part of brackets 83,as shown in Figs. 7 and- 8, each bracket having jaws 84 for embracingone of the flanges of the beam and set-screws 85 for securing thebracket to the beam, so that it between which the web or eece deliveredby the conveyer belt or apron 2` passes and by which such web or fleeceis laid upon the upper run of the conveyer belt or apron 21, whichtravels in a direction at right angles to the travel of theconveyer-belts 1 and 2, the vertical adjustability of the rods 18 on thecarriage 7 providing for the disposal of the drums 19 and 2O at anydesired distance from the upper run of the belt or apron 21, dependingupon the thickness of the web which is being acted upon. Y. l

To the upper end of each of the rods 18 is pivoted a lever 22, onearrn'of which carries a weight 23, the other arm of the lever having apulley or sheave 24, around which passes a belt. 25, which also passesaround pulleys 26 on the shafts ofthe drums 19 and 2O and at anintermediate point is caused to pass around or'in contact with a pulleyor sheave 27 on the shaft or drum 6, thereby imparting movement inopposite directions to the-dru ms 19 and 20, so that they will properlylay the web or fleece upon the upper run of the transverse belt or apron21, the weighted lever 22 keeping the belt 25 under normal tension,which is not interfered' with by the vertical adjustment of the drums 19and 20. These features are shown most fully in Fig. 5.

The endless driving-chains 11 are carried at their outer ends by sheavesor pulleys each mounted upon a stud 28, carried by a bracket 29, whichhas a projecting foot embracing the lower flange of the beam and,secured thereto by a set-screw 31, as shown in Fig. 6, so as toconstitute a clamp whereby the bracket 29 can be secured upon the beamin any desired position of longitudinal adjustment and the chain `belts11 can thus be kept under proper tension.

In order to compact the web or lieece carried by the endless belt orconveyer 2, I secure to the side beams 14 of the camel-back framebrackets 32, which receive the boxes for the journals of rollers 33, thelatter resting upon the web or fleece as it is carried by saidconveyer-belt 2.

At one end of its run thetransverse belt or conveyor 21 passes arou nd adrum 35,the shaft.

ings on the frame 38, has at one end a pulley 41 for receiving asuitable `driving-belt and at the other end a spur-pinion 42, whichmeshes with a spur-wheel 43, turning on a stud projecting from saidframe 38, this spur-wheel having a crank-pin 44, connected by a link 45to an arm 46, hung so as to swing freely upon a shaft 47, to which issecured the drum 48, whereby the endless belt 21 is driven, the shaft 47also having secured to it a ratchet-wheel 49, with which engages a pawl50, hung to the arm 46. Hence as the spur-wheel 43 is rotated the arm 46will be caused to swing upon the shaft 47, andintermittent movements ofpartial rotation will be im parted to the ratchet wheel 49, and hence tothe shaft 47 and drum 48, so as to cause intermittent forward movementsof the conveyer belt or apron 21, the extent of each movement beingdependent upon theadjustment of a segmental shield 51, loosely mountedon the shaft 47, and which can be adjusted so as to cover more or lessof the teeth of the ratchet-wheel within the limit of swing of the pawl50, thus determining the number of teeth which remain in action,andconsequently the degree of fractional rotation imparted to theratchet-wheel on each swing of the arm 46.

In advance of the drum 48 are a pair of press-rolls 52 and 53, thebearings of the upper roll being suitably controlled, so that anydesired amount of pressure may be imparted to them, and the shaft of thelower press-roll is driven from the shaft 47 through the interventionot' three spur-gears 54, 55, and 56, as shown by dotted lines in Fig. 3,the spurwheel 54 being secured to the shaft 47, the spur-Wheel 56 beingsecured to the shaft of the lower drumv 52, and the spur-wheel beingcarried by a swinging arm mounted upon the shaft 47, so that it willproperly mesh with the spur-wheels 54 and 56 vand will impart to thelower press-roll 52 movement equal in surface speed to the speed of thebelt 21, whereby the web or vfleece will be drawn forward by thepress-rolls 52 and 53 just as fast as it is delivered by the belt 21.

A sprocket-wheel 58 on the shaft of the drum 52 drives, by means 0f achain 59, a

sprocket-wheel 60 on the shaft of a drum 61, y

this shaft being mounted in suitable bearings on the Vframes 38 andserving to drive the shaft of another and similar drum 62 through theintervention of spur-gears 63, 64, and 65. (Indicated by the dottedcircles in Fig. Hence both of the drums 61 and 62 will be rotated in thesame direction and at the same surfacespeed.

The drum 66, upon which the bat is to be wound, rests upon the drums 61and 62 and as the bat is wound thereon rises, each spindle of the drumbeing adapted to a bearing in a Weight 67, which can slide upon a bar68, mounted on the frame 38, this Weight determining the degree ofcompactness with which the bat is Wound upon the drum 66. When the useof the weight is not desired, it may IIO be raised to the "top of thebar 68 and secured thereto by means of a locking-screw 69. In order toguide the journals 4of the drum 66 when the weight 67 is not employed, Imay remploy a bar 67a, held in upright position by a catch 68, so thatit can be readily released when it is desired to insert or remove thedrum 66.

In order to support the web or fleece in its passage from the rolls 52and l53 to the drum 6l, I employ 'an intermediate supporting-roll 70, asshown. by dotted lines in Fig. 3, this roll being driven from the shaftof the drum 6l through the `medium of sprocket-wheels 7l and 72 and achain 73 or other equivalent power-transmitting device.

When itis desired to deposit upon the web or fleece upon the 4conveyerbelt or apron 21 a coating of size for the purpose yof uniting thesurface fibers of the web or securing together successive webs depositedthereon, I

. employ one or more sizing devices, such as shown in elevation in` Fig.3 and in section in Fig. 9, these sizing devices being suitably locatedupon the frame 37. On reference to Fig. 9 it will be .observed that thesizing device comprises a pan 75 for containing the glue or other sizingfluid, in which is partially submerged adrum 76, the shaft of which isadapted to `vertically-adjustable bearings in side frames mounted uponthe beams 37. vertically-adjustable bearings carry the shaft of arotating brush 77, thijs brush-shaft and the shaft of the drum 76 beingsuitably connected, so that said brush and drum will rotate in thedirections of their respective arrows, Fig. 7. Upon suitable uprightstuds 78 on the side frame is mounted so as to be vertically adjustablea blade or strip 79, which can be adjusted from and toward the brush 77so as to project to any desired extent into the mass of fibers orbristles constituting said brush. Henceas the latter rotates it willgather the liquid glue or other sizing compound from the surface of thedrum 76, and when the fibers or bristles are first bent backwardly andthen suddenly released by contact with the blade 79 the sizing liquidthus gathered by said fibers will be forcibly thrown or projectedmntothe surface of the web or fleece `upon the endless belt or conveyer 21,and a continuous rain or sprayl of the sizing fluid thus caused todescend upon said web or fleece, so as to impart a uniform covering orcoating of 4size to the latter as it is carried forward by the conveyer.

In forming a multiple bat I combine with the single conveyer belt orapron 2l a series of carding or garnet machines, each with itscamel-back lapper, as shown, for instance, in

Fig.V 10, in which three of such devices are shown, the web or fleecefrom the second machine being laid upon that from the first machine and`the web or fleece from the third machine being laid upon the twopreviously i deposited. By this means I can readily form a bat havingany desired thickness and having outer layers of good material andaninterposed layer or layers of inferior material.

Having thus described my invention, I claim and desire to secure byLetters Patent- I. The combination of the reciprocated carriage of acamel-back lapper, a transverse conveyer belt or apron, a pair of drumsbetween which the web or fleece passes from the conveyer of the lapperto the transverse belt, a driving-belt for-imparting rotating movementto said pair of drums, and a weighted lever carrying a sheave aroundwhich said drivingbelt passes, substantially as specified.
